Therapeutic agent preparations into a lumen of the intestinal tract using a swallowable drug delivery device

Abstract

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Many embodiments provide a swallowable device for delivering the agents. Particular embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. Embodiments also provide various drug preparations that are configured to be contained within the capsule, advanced from the capsule into the intestinal wall and degrade within the wall to release the drug to produce a therapeutic effect. The preparation can be coupled to an actuator having a first configuration where the preparation is contained in the capsule and a second configuration where the preparation is advanced out of the capsule into the intestinal wall. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

What is claimed is: 
     
       1. A therapeutic preparation for delivery into a lumen of the intestinal tract, the lumen having a lumen wall, the preparation comprising a therapeutically effective dose of at least one therapeutic agent, wherein the preparation is configured to be contained in a swallowable capsule and operably coupled to an actuator having a first configuration and a second configuration, the preparation being contained within the capsule in the first configuration and advanced out of the capsule and into the lumen wall in the second configuration so as to deliver the therapeutic agent into the lumen wall. 
     
     
       2. The preparation of  claim 1 , wherein the lumen is the small intestine and the preparation is configured to degrade within the wall of the small intestine. 
     
     
       3. The preparation of  claim 1 , wherein the preparation comprises at least one pharmaceutical excipient. 
     
     
       4. The preparation of  claim 1 , wherein the preparation is configured to have a selectable surface area to volume ratio to achieve a selectable rate of release of the therapeutic agent in the lumen wall. 
     
     
       5. The preparation of  claim 1 , wherein an amount of the therapeutic agent within the preparation to produce a desired therapeutic effect is less than an amount to produce a corresponding effect if the agent was orally delivered without containment in the swallowable capsule. 
     
     
       6. The preparation of  claim 1 , wherein the preparation is configured to be delivered within a lumen of a tissue penetrating member. 
     
     
       7. The preparation of  claim 1 , wherein at least a portion of the preparation is shaped as a tissue penetrating member advanceable into the lumen wall, the tissue penetrating member having a pointed tip. 
     
     
       8. The preparation of  claim 1 , wherein the therapeutic agent comprises a therapeutically effective dose of insulin for the treatment of diabetes or a glucose regulation disorder. 
     
     
       9. The preparation of  claim 8 , wherein the dose of insulin is in a range from about 4 to 9 units of insulin. 
     
     
       10. The preparation of  claim 1 , wherein the therapeutic agent comprises a therapeutically effective dose of an incretin for the treatment of diabetes or a glucose regulation disorder. 
     
     
       11. The preparation of  claim 10 , wherein the incretin comprises a glucagon like peptide-1 (GLP-1), a GLP-1 analogue, exenatide, liraglutide, albiglutide, taspoglutide or a gastric inhibitory polypeptide (GIP). 
     
     
       12. The preparation of  claim 11 , wherein the incretin comprises exenatide and the dose is in a range from about 1 to 10 μg. 
     
     
       13. The preparation of  claim 11 , wherein the incretin comprises liraglutide and the dose is in a range from about 1 to 2 mg. 
     
     
       14. The preparation of  claim 1 , wherein the therapeutic agent comprises a combination of therapeutic agents for the treatment of diabetes or a glucose regulation disorder. 
     
     
       15. The preparation of  claim 14 , wherein the combination comprises a therapeutically effective dose of an incretin and a therapeutically effective dose of a biguanide. 
     
     
       16. The preparation of  claim 15 , wherein the incretin comprises exenatide and the biguanide comprises metformin. 
     
     
       17. The preparation of  claim 15 , wherein the dosages of the incretin and the biguanide are matched to produce an improved level of blood glucose control for an extended period. 
     
     
       18. The preparation of  claim 1 , wherein the therapeutic agent comprises a therapeutically effective dose of growth hormone. 
     
     
       19. The preparation of  claim 1 , wherein the therapeutic agent comprises a therapeutically effective dose of parathyroid hormone for the treatment of osteoporosis or a thyroid disorder. 
     
     
       20. The preparation of  claim 1 , wherein the therapeutic agent comprises a therapeutically effective dose of a chemotherapeutic agent for the treatment of cancer. 
     
     
       21. The preparation of  claim 1 , wherein the therapeutic agent comprises a therapeutically effective dose of an antiviral compound.
